(Updated at 2:55 a.m.) Arlington County Police are investigating a serious pedestrian accident on a busy street in the center of Clarendon.

An adult male was struck by a Honda Civic coupe heading eastbound on Clarendon Blvd, near the intersection with N. Highland Street, around 12:30 a.m., according to initial reports. The man suffered life-threatening injuries and was transported via ambulance to George Washington University Hospital.

Police shut down Clarendon Blvd from Washington Blvd to N. Garfield Street while detectives investigated the accident. Crowds of Clarendon bar-goers peered from behind yellow police tape at the bloody evidence marked at the scene, including the victim’s shoes, pants and shirt.

Police on the scene told ARLnow.com that charges were pending against the driver of the Honda. Unconfirmed witness accounts suggested the victim was crossing outside the crosswalk and was struck by the car, which was traveling through the intersection at what was described as a relatively high rate of speed. The victim flew through the air and came to rest, motionless, on the pavement, a witness said.

As of 2:15 a.m., a police accident reconstruction team was taking photos and using measurement devices to piece together a more definitive account of how the accident happened. The on-scene investigation is expected to last for several more hours, we’re told.
